| Abstract: | The strtictures and phase transitions of thermotropic liquid crystalline aromaticcopolyesters based on p-hydroxy-benzoic acid(PHB) ,terephthalic acid(TPA)and bisphenolA(BPA) were studied by DSC,WAXD,and hot stage polarized microscopy.The effects ofannealing and shearing on the microstructures and seqtience structures of the copolyesterswere discussed emphatically,The two glass transition temperatures occurred in sample with50%PHB bave been discussed. |

| Keywords: | thermotropic liquid crystalline copolyester microstructure oriented structure glass transition |
